[急]AMESim7.0仿真出现问题，请高手帮忙！

我装的AMESim7.0能搭建模型，而且前段时间我还用的挺好的，突然前两天在仿真的时候就出现问题了，在log里出现如下文字：
Requesting hydraulic license ...
got the license for hydraulic, continuing
Requesting amesim_runtime license ...
got the license for amesim_runtime, continuing
Requesting hcd license ...
got the license for hcd, continuing
Total CPU time: 0.172 seconds
AMESim model D:/AMESim/7.0.0/demo/Libraries/HCD/PressureRegulator_ terminated normally
只要是点仿真就出现这样的结果，软件里自带的例子也一样，请问是不是我的许可文件有问题了？哪位高手给解答一下，小弟正做毕业设计，很急！
